The Measure of Man

Founding Legions

The First Founding Legions were crafted by the Emperor himself, in the image of his twenty Primarchs. They forged the Imperium in bloody combat as they waged the Great Crusade across the galaxy. Many Space Marines fell to the maligned seduction of Chaos during the Horus Heresy, but those that stayed loyal formed the base from which all Space Marine Chapters would be created. Those Chapters that still hold the loyalist Legions’ names and colours are the oldest and most revered of all the Adeptus Astartes. Below is a list of each of the First Founding Legions, their Primarchs, and the worlds from which each Primarch was found. Each Legion, Primarch, and planet is also a link that will take you to the appropriate Wikipedia page to help you expand your research:
